Beam connection

[emphasis303]

Hello Everyone

I just wanted to know if you had a beam connection where the supporting beam is running perpendicular to the beam it is going to support and you are connecting the beam via a bolted method to the webs of both beams, what would be the best connection to use to resist the anticipated forces being imposed, shear etc.

Beam A is the supporting beam and beam B is the beam that is supported, now if beam A is also supporting a 3 storey solid double skin brick wall and 3 floors all constructed of 8x2 timber joists and then is going to be supporting beam B by its web as well and beam B is supporting a double skin brick wall 1 storey high, what would you use?

Both beams are 254 x 146s

Angle cleat, fin or flexible end plate connection etc?

Also what size bolts would be suitable m20 in 22mm holes?

Many Thanks

The connection detail should be designed same as the beam would be

Thanks

Does anyone know whether the different types of connections come in different sizes or grades etc?

To be honest this sort thing has to be specified by a structural engineer and passed by building control once in place.
Many forces are being placed on these beams and it all has to be calculated properly.

Yes they do

The loads on beam A have no impact on the connection design where beam B is the supported beam. The type of connection used should be suitable for the loads applied and it should also be the most suitable regarding ease of fitting into place and inserting bolts etc.

The main checks will be bolt shear, bolt bearing (on web and/or connecting plate), weld shear, and depending on the connection type, possibly weld tension.
If the beam is notched, the capacity at the notch should also be checked.

If the beam is lightly loaded then the connection may be OK by inspection without needing to carry out all of those checks, but either way, your engineer should have designed the connection for you.
